Abstract

-dioctyl-3,4,9,10-perylene tetracarboxylic diimide (PTCDI-C8H) thin films have been implemented into organic thin-filmfield-effect transistors. Mobilities up to 0.6 cm2 V−1 s−1 and current on/off ratios were obtained. Linear regime mobilities were typically half of those measured in the saturation regime. X-ray studies in reflection mode suggest a spacing of ∼20 Å for thin evaporated films of PTCDI-C8H, which is consistent with the value of obtained from our simulations when an interdigitated packing structure is assumed.
